ARTHUR W. BEARDSELL, OF MILFORD, MASSACHUSETTS, ASSIGNOR TO DRAPER COMPANY,

OF I-IOPEDALE, MASSACHUSETTS, A CORPORATION OF MAINE.

RING SPINNING OR TWISTING APPARATUS.

Application filed December 4, 1907.

T all whom it may concern:

Be it known that I, ARTHUR W. BEARD- SELL, a citizen of the United States, and resident of Milford, county of Worcester, State of Massachusetts, have invented an Improvement in Ring Spinning or Twisting Apparatus, of which the following description, in connection with the accompanying drawing, is a specification, like letters on the i drawing representing like parts.

This invention relates to spinning or twisting apparatus of the so-oalled rotary ring type, wherein the rotation of the ring is effected by the pull of the yarn acting through the traveler, and the object of my present invention is the production of means whereby the traveler is assisted to effect rotation of the ring. T 0 this end I have provided, in rotary spinning-ring apparatus, means to cooperate with the yarn independently of the traveler, so that some of the ring-rotating strain is taken ofi of the traveler.

The various novel features of my invention will be fully described in the subjoined specification and particularly pointed out in the following claims.

Figure 1 is a top plan view of spinning or twisting app aratus embodying my invention; Fig. 2 is a side elevation thereof; Fig. 3 is a diametral section on the line 33, Fig. 1.

The main ring 1 is shown of the double flange type, having its upper flange 2 forming a raceway for the traveler 4, revoluble on the ring, the lower flange 3 of the ring resting in shouldered seats 5 formed on block-like portions 6 of the annular ring-holder 7, which in practice is secured to the ring-rail in any suitable manner. A fiat, annular downhold S, detachably secured by screws 9 to the parts 6 of the ring-holder projects above and overhangs the flange 3, limiting axial movement of the ring, see Figs. 2 and 3, while permitting rotation thereof under the pull of the yarn.

In practice the downhold may be made in halves, as shown in Fig. 1, to facilitate the application or removal of a ring from the ring-holder.

The pull of the yarn as it passes from the traveler to the bobbin B acts to effect rotation of the loosely held ring, in a manner familiar to those conversant with rotary-ring apparatus.

In order to assist in the rotation of the Specification of Letters Patent.

with the yarn independently of the traveler.

Herein such means consists of an auxiliary annular member, shown as a relatively thin cylinder or ring 10, located within and concentric with the main ring 1, and fixedly connected therewith, as by a driving fit between the flange 11, Fig. 3, of the auxiliary ring and the inner circumference of the flange 3 of the main ring.

The upper edge of the auxiliary ring is made wavy or corrugated, as at 12, at substantially the height of the yarn as it passes from the traveler to the bobbin. The yarn 1! runs over this wavy edge, Fig. 2, and the contact between the yarn and the auxiliary ring assists in making the ring revolve, and relieves the traveler of some of the work to which heretofore it has been subjected.

By assisting the traveler in rotating the ring, and thereby relieving it of some of the work, the traveler will wear longer and better,

and the operation of the apparatus as a whole is improved.

The auxiliary ring or member 10 may have one or more openings 13, Fig. 3, for the escape of lint or dust collecting in the space between the two rings.-

My invention is not restricted to the precise construction and arrangement herein shown and described, as the same may be modified in various particulars by those skilled in the art without departing from the sp rit and scope of my invention as expressed in the claims appended hereto.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. The combination, in spinning apparatus, of fixedly connected main and auxiliary rotary rings, and a traveler revoluble on the main, outer ring only, the yarn directly engaging the auxiliary ring as it passes from the traveler and thereby assisting in effecting ro tation of the main ring.

2. The combination, with a rotary spinning-ring, and a traveler revoluble thereon, of an annular auxiliary member within and carried by the ring and having a wavy upper edge, to engage the yarn as it passes from the traveler to the bobbin.

3. The combination, with a rotary spinning-ring, and a traveler revoluble thereon, of means carried by the ring independently of the traveler to cooperate with the yarn and assist in rotating the ring.

4. The combination, with a rotary spinning-ring, and a traveler revoluble thereon, of means rotating in unison with the ring to cooperate with the yarn independently of the traveler and between it and the bobbin and assist in rotating the ring. a

5. The combination, with a rotary spinning-ring, and a traveler revoluble thereon, of a thin metallic cylinder concentric with
